Julie began to slowly and rhythmically grind her hips against Chelsea's bare buttock as if she was fucking her step-daughter from behind. She turned her head to the side to receive a deep sensuous kiss from Melanie who had raised herself slightly on the bed in order to be face to face with her sexual mentor. She felt Melanie's hand caressing her buttocks for a few moments, and then felt her fingers trace a line down the crack of her butt and settle on the wet outer lips of her vagina, where they teased and rubbed her moist labia lips for several long moments. Julie let out a loud sigh of pleasure when she felt two of Melanie's fingers slide in.
Julie could feel the level of lust in her body rising, but was still enough in control to realise that the night was for Chelsea. She stopped her grinding and pulled Melanie's hand away from her wet pussy.
"I think you're ready for Zach to do his thing now baby." The sexual tension Julie felt coursing through her body made her voice sound husky.
Julie and Melanie moved to lie on either side of the two still grinding bodies on the bed. Julie carefully and slowly removed the butt plug from Chelsea's anal opening and wrapped it in a towel that she had placed on the bedside table. In a very gentle tone she suggested to Chelsea that she might find it more comfortable to be on her hands and knees with Zach behind her as she could control the depth and speed of the fucking better from there. She and Melanie helped Chelsea off Zach and put her in the right position at the other end of the bed.
"Come on lover boy, now's not the time to be shy," Melanie teased Zach while she took hold of his engorged cock and gave it a playful squeeze.
With soothing words and gentle touches Julie and Melanie knelt on either side of Chelsea's hips and directed the actions between Zach and Chelsea as if they were guiding a large truck into the tightest of parking spaces. Julie took charge of positioning her step-daughter's hips while Melanie ensured that Zach's out-thrust cock was well lubricated as she guided him closer to its target: the brown wrinkled opening between Chelsea's deliciously round globes. Julie added a final squirt of lube to the tight puckered hole, pushing some of it in past the gripping outer layer of muscles, then pulled Chelsea's cheeks apart as wide as she could.
Zach looked down and saw Melanie guide the tip of his knob against Chelsea's tight opening. He felt the sweet young girl's hand behind his back pushing him slightly, and as he shuffled forward the last few inches he saw his domed cock-head press against Chelsea's wrinkled crevice. At first the tightness of Chelsea's sphincter muscle prevented his entry, then as he added a little more pressure it popped in.
Zach heard Chelsea's sharp intake of breath, and stopped where he was with only his knob in her ass. He saw her reach her hand between their legs and felt it take hold of his scrotum, gently pulling on it to pull him deeper into her, at the same time pushing her hips back at him. As his cock slowly glided all the way in he was aware of the familiar sensation of its entire length being gripped tightly along the whole shaft from his earlier anal sessions with first Julie, and then more recently with Melanie. As familiar as it felt, it still took his breath away, and he slowed down to savour the exquisiteness of the how it felt.
A load moan erupted from Chelsea's mouth. She felt as though the back half of her abdomen had been completely filled up. She released her hold on Zach's ball sac and moved her hand to her wet cunt lips, and began to rub on her sensitive clitoris.
"Oh... oh... this feels so fucking good! Keep fucking me like that baby!" Her words and the tone of her voice told Zach that she was enjoying her first anal experience.
Julie and Melanie were still kneeling on the bed either side of Chelsea, and had begun to slowly run their fingers across her back, or caress her breasts or her thighs. They took it in turns to give Zach an occasional sensual kiss, and to run their fingernails across his chest so that he wouldn't feel left out in any way. They both enjoyed their grandstand seat of the action as they had a birds-eye view of the tight grip of Chelsea's sphincter muscle around Zach's slick shaft as it slowly slid in and out of her back passage.
After a few minutes Julie leaned across her moaning step-daughter's back to give Melanie a kiss and to stroke her erect nipples and to flick on her nipple rings.
"I don't think these two need our help anymore," she said to Melanie, nodding towards the comfortable armchair by the window where she suggested they could still watch and play with each other at the same time.
They both climbed off the bed carefully so as not to disturb the steady rhythm that Zach and Chelsea had settled into. As she stepped over to the armchair Julie paused at the foot of the bed and reached into her tote bag to retrieve something. Melanie felt a flutter of excitement in her loins when she saw what Julie pulled her out of the bag. Julie had her hand wrapped around her favourite double ended dildo in its strapon harness.
Melanie quickly helped Julie with her end of the dildo and the strapon harness. After Julie made the last couple of adjustments so that everything was comfortable inside and outside, she sat on the armchair and opened her arms wide to receive the younger girl. Melanie took hold of the external end of the dildo and sat down on Julie's lap, carefully sliding the firm silicone phallus into her own pussy as she did. As she felt the cock-like shape slide snugly into place inside her, she shivered and gave a whimper of pleasure, grinding her hips into Julie beneath her.
Julie wrapped her arms around Melanie's body and let her hands run all over her upper torso, between her legs, and down along her thighs. Her left hand eventually settled on the younger girl's left breast, which Melanie covered with her own, and her right settled on the outer lips of her vagina. She leaned her head forward and kissed Melanie's exposed neck, and when the younger girl turned her head slightly, her kisses moved to her lips. After a few moments they settled back to watch Zach's and Chelsea's sexual display, all the while grinding their own hips against each other in response.
From her doggy position on the bed, Chelsea was aware that her step-mother and Melanie had something going on away from the bed, but with her face pressed into the pillows she couldn't see what it was. With a quick look over her shoulder she suddenly understood the other two women had their own hot scene going. She felt the desire to watch them as strongly as she felt the desire to be fucked anally by Zach.
"I want you on your back so that I can lie on top of you," she said over her shoulder between moans.
Zach had also been aware of some other sexual activity taking place somewhere behind him and to the side. He did as requested, and flipped over onto his back after he had carefully pulled his cock out of Chelsea. Once Chelsea had slowly lowered herself onto Zach's still-hard cock, carefully reintroducing it into her anus, they could both lie back and grind their bodies against each other as they watched the action going on between Julie and Melanie a mere few feet away from them.
Both copulating couples watched each other intently. Zach and Chelsea could see Julie whispering in Melanie's ear, one hand playfully tweaking her youthful nipple or tugging on its ring, the other moving between her legs, their hips grinding against each other in unison. They watched as Melanie pushed Julie's hand between her legs away so that she could begin her own urgent rubbing, the pouty lips of her mouth open and drawing in deep gulps of air, all the while watching looking back at them lustfully.
Julie and Melanie could see Chelsea's wide open legs, splayed out wide on either side of Zach's, and watched mesmerised as she pushed her hips downwards into his upthrusts. They could see the puffy wet lips of her vagina and the glistening moisture of her pussy juices coating her inner thighs and slowly dribbling down onto Zach's hard cock as it pistoned in and out of the tight other hole underneath. They felt a little surge of erotic excitement as Chelsea reached her hand down and thrust three fingers deep into her own cunt, moving them around vigorously for a few moments before pulling them out to suck deeply on them.
The sight was too much for Melanie, and she almost started to bounce on Julie's lap while rubbing furiously on her clitoris and flicking on her clit ring. Her eyes rolled upwards, she lifted her head as if to scream and began to shudder as her orgasm took control of her body for what seemed an eternity. After her spasms had subsided, Melanie carefully turned her body sideways so that she could give Julie a deep kiss, then they both looked over at the couple on the bed.
"Zach darling, I want you to stay where you are in my ass. Mel honey, I hope you don't mind, but now that you've cum I'd like Julie to fuck me," Chelsea called out from the bed.
Melanie laughed, "Sure baby." She lifted herself off Julie and offered her a hand to pull her up.
Julie walked across to the bed, and knelt astride Zach's legs again, but this time she raised her step-daughter's legs so that they rested on her own shoulders, exposing the dripping opening of her pussy. She shuffled forwards slightly until the bulbous head of the strapon rested against the entrance to her vagina. She hesitated for a moment until she saw the steely look in Chelsea's eyes and the determined nod that accompanied it. She pushed forwards and half the dildo's shaft entered. At another nod from Chelsea she pushed again, and the dildo sank all the way in till step-mother's and -daughter's pubic mounds rested against each other.
With Zach lying underneath her and his entire length pushed deep into her rectum, and Julie lying on top of her with her strapon buried up to the hilt, the sensations Chelsea felt were unlike anything she had ever felt before. She was sandwiched, and every single nerve in every pleasure centre in her body seemed to going into overload. Every direction she pushed her hips resulted in little explosions of pleasure, as did every little movement from either Julie or Zach.
"Oh god, I feel so fucking filled up, I can't believe how good it feels!" Chelsea screamed between clenched teeth.
Julie glanced over her shoulder at Melanie, who sat glassy-eyed on the armchair with her hands busily rubbing and stroking her pussy, intently watching as the hot and sexy scene played out in front of her.
"You can come up and join us on the bed Mel honey. I'm sure Zach would love to help you with your pussy."
Melanie didn't need to be asked twice, and quickly climbed back onto the bed alongside Zach's head. She faced the foot of the bed so that she could watch Julie slowly fucking Chelsea. She carefully lifted Chelsea's head so that it could rest against her abdomen, and lowered herself to squat over Zach's face. She lowered herself further until she felt his tongue flicking at and sucking on her cunt lips.
Despite being at the bottom of the human sandwich Zach did not feel uncomfortable. He was able to keep up a steady rhythm thrusting his hard cock in and out of Chelsea's deliciously tight ass, and when he felt Julie fucking her with her strapon as well, he could feel the occasional contact of the dildo rub against his penis through the thin membrane that separated the two. And now that Melanie had lowered herself onto his face, he felt like he had gone to heaven. He could taste her delicious female juices, and eagerly lapped at the steady flow as it seeped from her sexual orifice. He could feel her squirm when he stuck his tongue as far as it could go in her hole.
"Oh god, fuck me harder, I'm almost there!" Chelsea screamed.
Julie began to thrust harder into her step-daughter, pushing the strapon as far as it could go into her young vagina, at the same time she felt the other end push back into her own sex hole. She leaned down to kiss Chelsea hard on the lips, groaning as she felt her own body begin to respond to the intense eroticism of the sexual stimuli all around her. She pulled back and raised her head to continue the kiss with Melanie, who had leaned forward herself in search of a kiss.
"Oh fuck... oh fuck... I'm cumming!" Chelsea squealed through clenched teeth, her body rigid, her hands gripping the bed sheets tightly.
Julie immediately reached down behind and underneath her own thighs to run her long nails against Zach's balls. It proved to be too much, and Zach felt as if a dam had burst and the deluge he had been trying to hold back for the last few minutes erupted outwards from deep within the pit of his loins. He felt his cum shoot along his shaft and spew into the back recesses of Chelsea's rectal cavity.
All four on the bed slowed their movements to an eventual stop. They laughed and teased each other about how much one or other had moved, and had nearly upset the whole apple cart. Melanie was the first to move as she climbed off the bed and stood back to see if she could offer anyone any assistance. Zach's softening cock slowly slipped out of Chelsea's slightly stretched ass at the same time that Julie slid the strapon out from her puffy cunt.
Chelsea and Zach were helped onto their feet by Julie and Melanie, and then ushered towards the en suite bathroom to clean themselves up. Chelsea sat on the toilet and expelled as much of Zach's cum as she could, then carefully cleaned herself and Zach up.
"I hope I didn't hurt you." The concern in Zach's voice and his look was very obvious.
"It only hurt a little, but once you were in it was such a turn on that it felt like all I wanted to do was cum again and again." Chelsea pulled his head down for a long kiss.
"Besides, you're way too caring and gentle a person to hurt anyone." She prodded him in the ribs and laughed at his embarrassment.
The sight that greeted them when they returned to the bedroom stopped them in their tracks. Julie was on all fours on the bed, a thin film of sweat covered her back and her arms. Melanie was wearing the strapon that Julie had been wearing only a few minutes earlier, and was kneeling behind her as she fucked her furiously. Both looked up from the bed and smiled at Zach and Chelsea at the doorway.
"She hasn't cum yet, so I'm helping her get there. You can join us if you like." Melanie had a mischievous look on her face.
Chelsea stood in front of Zach's right shoulder. He felt her left hand slowly reach back to take hold of his penis. He knew she was getting turned on again, standing there watching Julie being fucked by their co-lover, and he had to admit to himself that he was too. The sounds of lovemaking coming from the bed were a steady and continuous stream of moans and whimpers as Melanie pounded into Julie mercilessly with the strapon.
Without thinking, his right hand reached around and took hold of Chelsea's right breast, and began to pinch and pull on the nipple. She leaned her head back slightly and offered her soft lips for a kiss, an offer Zach was only too happy to accept. He looked down and saw that her right hand was moving somewhere between her legs. Her left hand had started to stroke his cock back to life, and he could feel himself starting to get hard once more. Once he was fully hard Chelsea took a gentle but firm hold and led him towards the bed, where she knelt down on all fours beside her step-mother and indicated for Zach to get into position behind her.
As Zach shuffled into position he could see the damp gash between Chelsea's upper thighs, so he knew her vagina was ready for him. He leaned slightly to his left to give Melanie a sensual kiss while she pumped away behind Julie's open thighs. Without wasting any more time he rubbed his cock head against Chelsea's wet slit, causing her to squirm and moan. He leaned into her slightly and felt his cock slip effortlessly into her wet cunt hole, drawing another deep moan from her mouth.
With their faces just inches apart, their eyes watching each other, Julie and Chelsea moved their heads closer and pressed their lips together to share a long passionate kiss. They held hands while their respective lovers pumped away at their cunts behind them.
Melanie concentrated on keeping a steady pumping rhythm with her hips and reached a hand behind her to the foot of the bed to grab Julie's tote bag by the loop. She placed it in the middle of Julie's back and rummaged around until she found what she was after. When she withdrew her hand she had a small bottle of lube, a long pink vibrator shaped like a bullet on the end of a flexible wand, and a more traditional styled blue vibrator. She pushed the tote bag back behind her with her other hand and offered Zach his choice of the two toys with a wink.
Zach selected the wand, and watched as Melanie dribbled a few drops of lube onto the crease of both backsides before them. Using a hand for each backside she then rubbed the lube all around the two brown wrinkled crevices, pushing a little of the thick slippery liquid in past the tight outer muscled ring. Step-mother and -daughter both moaned when they felt the intrusive finger, but it was clearly a moan of pleasure as both backsides pushed back at the intruder, allowing it to slide in further.
Melanie winked once more at Zach and removed her probing fingers from Julie's and Chelsea's backsides. She quickly wiped her hands on a towel she had placed by her knees and took hold of the blue vibrator. She turned the toy on and lowered it so that the shaft rested against Julie's wrinkled brown rosette. She deliberately teased her older sexual mentor by running the tip of the noisy toy from the top of Julie's crease, past her puckered anus, and all the way down to the point just alongside where her strapon was still sliding in and out of her vagina.
The sensations drove Julie wild, and she began to hump and push back at Melanie's hips, deliberately trying to push the strapon deeper into her own cunt, and searching for the vibrator in the hope that it might slide into her anus as well. Melanie didn't keep her waiting too long, and slid the buzzing toy's tip past the outer lips of Julie's wrinkled hole and deep into her ass. Julie's response was immediate, an unintelligible cry of ecstasy and her hand reached back to grab at Melanie's hip and slam it forward into her.
Zach had followed Melanie's initial example and ran the buzzing bullet head of his wand up and down Chelsea's beautiful brown crease. Chelsea also responded with moans and sigh of pleasure, but it wasn't long before she reached her hand back with a silent request for the buzzing toy, which Zach was happy to hand to her. She took the wand between her spread thighs and pressed its head directly against her clit, and began to grind her pelvis against it.
Chelsea's familiar quiet whimpered oohs and ahs mixed with the step-mother's moans, and her jerking hips threatened to dislodge Zach's hard penis from its snug spot deep in her wet cunt. Not wanting to cum too soon, she reluctantly passed the noisy wand back to Zach, who quickly placed the vibrating tip against her steadily pulsing anal opening. Chelsea moaned and pushed her hips back hard at Zach. It only took a few short moments before her outer muscles relaxed to allow the knobby tip of the wand to penetrate further.
Chelsea pressed her face and breasts hard into the mattress, and the arching of her back raised her ass higher in the air, which allowed Zach a better access to her beautiful ass hole. He pushed the wand gently and felt the vibrating knob slide past her sphincter muscle, reaching deep in her rectum. He could feel the delicious sensation of its buzz through her thin anal membrane against the shaft and knob of his penis. He had to make an effort to concentrate on his breathing and on his rhythm as he slid in out of her wet cunt, or the sensations would push him over the top. He wanted to wait as long as he could so as to maximise both their pleasures.
